Exactly this. Replaced mine with HPB bulbs and love them. Still uses the OEM housing. Aftermarket housings have problems with fitment and water leakage.
Also, to the OP...for the record, ///M logos belong on ///M cars.

They're replacements are just plug 'n play. I have them and love them!

Same here, I have these and they fit very tight with no issues. I honestly could care less about the LEDs but I thought the OEM white lenses looked terrible on my jet black car, so I wanted smoked lenses to go with my blacklines. They look way better and with the LEDs they are much brighter than stock, so the smoked glass doesn't affect the actual function.

Not a fan of the WeissLicht side markers. Tried them on my e92 and one of the springs flung off when trying to install, difficult to fit on and there was a gap between the back of the light and the car. The description says that it includes a rubber gasket for OEM fit, but it does not. Also, the smoked ones seemed to have some sort of Zebra look to them. I went with EAS, fit is great, has the rubber gasket so no gap and no wierd Zebra stripe look.

Hello, have a 2006 325i, would like to swap all the signal and side marker light bulbs to LEDs, also license plate bulbs, all error free, anyone with knowledge about best bulbs to buy and link that are affordable and good quality ?

As others mentioned, the aftermarket options usually have poor fitment and or poor quality.

The HPB Side Marker upgrade replaces the bulb inside with LED's. You get the brightness and the fit and finish of OEM, win win.

For those that want a smoked look a bunch of customers have been smoking their OEM side marker with VHT Night shade.

Also, can brake bulbs can be swapped to LEDs? How will that look ?

Much appreciated!

Brake Bulb LED's will require coding last I recall, we tried this a few years ago and the white LED's washed out the brake lights cause they were so bright and it looked pink.

So you need RED LED's and they need to be 7watt or brighter to be worth it.
